    My '98 626 just started doing this today. The same exact symptoms... Engine light is blinking, severe hesitation and running very rough, and smells hot. It had been hesitating slightly when starting from a stop, but then ran normally until this morning.

Been in and out of the dealership and have had fuel injectors cleaned, then replaced, the catalytic converter replaced, the EGR valve replaced, O2 sensor..... just learned to live with it. NOW, it is running very rough and instead of the light on steady, it is now FLASHING!!! Where do I start?????

Test the temperature sending unit.  most mazdas built after 1998 have 2 of sending unit is for the the guage in the dash, the other sending unit goes to the vehicle computer, which in turn controls the idle and fuel to air ratio for the vehicle. if it is getting a bad signal or none t all it thinks the car is still very cold and causes it to run ruff and the light stays on  till reset

Check engine light on in 93 Lexus

The only way to check why the check engine light is on is to have autozone or a mechanic put a scanner on the car and read the engine codes. This will tell you exactly what is wrong. Many part stores will test it for free. Mechanics will charge about $40 But you will definately know exactly what the problem is.

If gauge is fine and car smells hot. It is probably due to plugged exhaust unless you have a wire laying on the exhaust manifold and it's melting.
